INTRODUCTION
1 PRODUCT DESCRIPTION
DigiWolf is a paddle owmeter capable of measuring the rate of a uid in a hydraulic circuit, and it can display the results of these measurements.
The device can also be set to control the lling of a tank by stopping the introduction of liquid once the required quantity has been reached (this function
is possible only by connecting the owmeter to the Pump Stop Module or the relevant cable - Par. 2.4-2.5).
1.1 Intended use
This device is designed to work on agricultural machinery for crop spraying applications.
The machine is designed and built in compliance with EN ISO 14982 standard (Electromagnetic compatibility - Forestry and
farming machines), harmonized with 2004/108/EC Directive.
The owmeter must not be used to measure the passage of hydrocarbons, ammable, explosive or toxic liquids. The owmeter
is not suitable for contact with liquids for human consumption.
2 FLOWMETER ASSEMBLY
Install the owmeter at least 20 cm from the elements that could cause turbulence inside the tubes (valves, bends, constrictions, etc.).
The owmeter can be installed in a vertical or horizontal position.
CAUTION:
- Do not t the owmeter with the display facing down (Fig. 1).
- The system must have a ltering element with a lter of at least 50 mesh, together with a safety valve to limit use pressure at
the specied max. valve (Tab. 2 - Par. 2.3.1).
OK
Assemble the owmeter using the suitable mounting parts (Fig. 2): t the bolts (M8) in their seats, then make them slide to their stop position to prevent
them from coming out.
OK OK
NO!
Fig. 1
The owmeter body must be assembled with the arrow on the label facing the ow direction.

2.1 Monitor rotation
Fig. 3
INSTALLATION
In case of vertical assembly, to simplify the use of the DigiWolf it is possible to rotate the
monitor by 90° with respect to the body (Fig. 3).
1) Remove the fork from the monitor using a screwdriver.
2) Remove the monitor from the owmeter body.
Fig. 4
Fig. 5
Fig. 6
If the monitor is turned upside down, the letters A and B can be seen: these correspond to
the two possible monitor positions (parallel and perpendicular to the body).
DigiWolf is supplied with the sensor in position A (parallel to the body).
With the aid of a screwdriver, loosen the screw locking the sensor without removing it.
Rotate the sensor anti-clockwise until reaching B stop position.

2.4 Electric connections
DigiWolf is designed to operate independently, but may be connected to ARAG devices (computers, monitors, displays) or equipment from
other manufacturers as long as they are set up for use with owmeters of this type.
DigiWolf can be powered by means of a generic power supply cable (cod. 4622BA50000.100 - not supplied), which does not allow the
operator to control lling functions directly from the device. Connections are listed in Table 3:
Cable colour Position Connection
Grey 1 GND
Brown 2 +12 VDC
Yellow/Green 3
Black 4 Pump control
For the use as lling owmeter, the DigiWolf must be connected to ARAG devices only.
IN CASE OF ELECTRIC ARC WELDING, MAKE SURE THAT THE POWER SUPPLY TO THE DEVICE IS DISCONNECTED; IF NECESSARY, DISCONNECT THE POWER SUPPLY CABLES.
ARAG is not liable for damages to the equipment, persons, animals or things caused by a wrong or unsuitable installation of the
owmeter. Failure to observe the above instructions automatically voids the warranty.

What follows applies to both operating modes of the owmeter.
7.1 Calibration
Rate reading may not be correct due to different system congurations (tubes, valve, etc.). Therefore, we recommend to make
a spray test; in case the measured value is different from the real one, perform an automatic calibration procedure or manually
calculate owrate constant.
7.1.1 Automatic calibration
Make a quantity of liquid previously measured or that can be measured with another system go through the owmeter. The greater the amount of
liquid used to perform the calibration procedure, the more accurate the calibration.
2) Access Automatic calibration menu (Setup menu > Calibration > Auto calibration). Once inside the menu, the device is ready to start measuring without
any further controls.
Fig. 33
3) Make the liquid go through the system. The display will start to show the increasing value of the measured quantity of liquid. Once liquid passage has nished,
the value on the display will not change any more.
At this point, press OK. In the lower part of the display, the message Stabi-
lization will come up and the device will show the screen on the side.

A) Press to toggle from one digit to another
B) Press in succession to modify the value of the digit highlighted by the cursor
C) Press to complete calibration procedure, or D) Press for 1 sec. to cancel calibration procedure.
If, after starting calibration, the device does not sense any ow passage (and the display remains in 0), press OK to exit the calibration
procedure without saving.
If the device continues to sense the liquid ow after pressing OK, after a few seconds the error message Stop flow!will be displayed.
